+# Input Data Formats
+
+Telegraf contains many general purpose plugins that support parsing input data
+using a configurable parser into [metrics][].  This allows, for example, the
+`kafka_consumer` input plugin to process messages in any of InfluxDB Line
+Protocol, JSON format, or Apache Avro format.
+
+- [Avro](/plugins/parsers/avro)
+- [Binary](/plugins/parsers/binary)
+- [Collectd](/plugins/parsers/collectd)
+- [CSV](/plugins/parsers/csv)
+- [Dropwizard](/plugins/parsers/dropwizard)
+- [Form URL Encoded](/plugins/parsers/form_urlencoded)
+- [Graphite](/plugins/parsers/graphite)
+- [Grok](/plugins/parsers/grok)
+- [InfluxDB Line Protocol](/plugins/parsers/influx)
+- [JSON](/plugins/parsers/json)
+- [JSON v2](/plugins/parsers/json_v2)
+- [Logfmt](/plugins/parsers/logfmt)
+- [Nagios](/plugins/parsers/nagios)
+- [OpenMetrics](/plugins/parsers/openmetrics)
+- [OpenTSDB](/plugins/parsers/opentsdb)
+- [Parquet](/plugins/parsers/parquet)
+- [Prometheus](/plugins/parsers/prometheus)
+- [PrometheusRemoteWrite](/plugins/parsers/prometheusremotewrite)
+- [Value](/plugins/parsers/value), ie: 45 or "booyah"
+- [Wavefront](/plugins/parsers/wavefront)
+- [XPath](/plugins/parsers/xpath) (supports XML, JSON, MessagePack, Protocol Buffers)
+
+Any input plugin containing the `data_format` option can use it to select the
+desired parser:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume.
+  data_format = "json"
+```
